Scammer Alert: Fraudulent "Insurance Refund" Calls Targeting Physician Practices
PRSM has clients that have received phone calls from alleged insurers asking for refunds recently. Generally, the caller cannot give any detail related to the claims. Our experience has been that insurers will not make the initial or even subsequent attempts to handle an overpayment by phone. So ask for detail and ask for it in writing. Do not give them your address—they should have it already.
Medical billing networks and physician practices are facing a rising wave of sophisticated "vishing" (voice phishing) scams. Fraudsters are now posing as commercial insurance payers or government contractors, calling clinical administrative staff to demand immediate refunds for alleged "reimbursement overpayments."
These high-pressure tactics exploit the complex nature of healthcare billing, but falling for them can lead to severe financial loss and compromised practice data.
How the Scam Unfolds
The caller typically uses caller-ID spoofing to mimic a legitimate insurance company and claims that a recent internal audit revealed a high-dollar overpayment on a batch of claims. To bypass standard, slower institutional accounting cycles, the scammer will pressure the practice staff to resolve the balance immediately over the phone using a corporate credit card, wire transfer, or digital payment portal.
Spotting the Red Flags: Protect Your Practice
Genuine insurance payers follow strict, highly regulated legal protocols for recouping funds. To protect your revenue and sensitive credentials, keep these rules in mind:
Demand Specific Claim Data: If a caller claims an overpayment occurred, ask for the specific Claim Number, National Provider Identifier (NPI), Date of Service, and Tax ID (TIN). Fraudulent callers will almost always stall or give vague answers because they lack access to your actual billing data.
Insist on Written Documentation: Legitimate payers do not initiate or handle recoupments over a casual phone call. True overpayments are processed via formal, written Post-Payment Review letters or automated offsets subtracted from subsequent Electronic Funds Transfers (EFTs). Always instruct the caller to send the formal overpayment demand notice in writing.
Never Provide Your Address: If a caller asks you to verify or provide your practice’s mailing address or corporate details so they can "send the paperwork," hang up. A legitimate payer already has your credentialing information and corporate address on file.
Verify Through the Provider Portal: Before taking any administrative action, independently log into your official payer portal (such as Availity or the insurer's proprietary dashboard) to check for active overpayment disputes or notifications.
The Bottom Line: Never authorize a financial transaction or surrender practice information over the phone based on an inbound call. If a representative demands an immediate refund, hang up and call the insurer back using a verified provider customer service number directly from their official portal.
